Abstract: Names of registered groups are displayed in a group name list section, and setting contents of authority for each function of a component mounting related application that is performable for a group selected from groups displayed in the table in the group name list section are displayed such that comparison between groups is possible. An administrator edits content for authority settings for each function while comparing between groups setting contents of authority for each function displayed in an account authority comparison display section. The administrator switches a display to and from a display all functions mode that displays content for authority settings by each function for all functions of the component related application such that comparison between groups is possible, and a display difference mode that displays setting contents only for functions for which the content for authority settings differ between groups such that comparison between groups is possible.

Abstract: The management computer of a mounting system, when productivity is lowered, identifies an operator and work type from a work history, retrieves a management value P for the identified work type for the identified operator, and increases the management value P by an increment of “1.” Then, the management computer of the mounting system, when judging that management value P is at least second threshold value P2, applies a performance restriction on the identified operator for the work of the identified work type. Thus, it is possible to curtail lowered productivity due to the same work by the same operator being repeated.

Abstract: Names of registered groups are displayed in group name list section 21, and setting contents of authority for each function of a component mounting related application that is performable for a group selected by an administrator from groups displayed in the table in group name list section 21 are displayed lined up such that comparison between groups is possible. An administrator edits content for authority settings for each function while comparing between groups setting contents of authority for each function of the component mounting related application displayed in account authority comparison display section 22.
